How should unused analog input pins (VnA/B and VnA/BGND) be terminated?Left Open, connect to GND, differential termination or else?
It is recommended to connect unused analog input to ground(GND) for optimal performance. How many channels of the AD7616 you are using in your application?
Looking at EVAL-AD7616 documentation in following link, I take it that
VxA/BGND: terminate to GND
VxA/B：terminate to GND through 270ohm
I referred to "Analog Input" in Table 3. Link Option, page 5, User Guide and EVB schematics.
Understood.Thanks a lot for your answer.10 to 16 channels. Actually it's under consideration.
